BOTTLE-CLOSING DEVICE.

SPECIFICATION forming part of Letters Patent No. 754,126, dated March 8,1904. Application filed February 6, 1902. Serial No. 92 ,889. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, FRANCIS B. CARY, 'of the city of Baltimore, State ofMaryland, have invented certain Improvements in Bottle-Closing Devices,of which the following is a speci: fication.

This invention relates to certain improvements in that class ofbottle-closing devices in which a spring-held valve operated by means ofa hand-lever is employed; and it consists in certain details ofconstruction of the same, as will be specifically pointed out in theclaim.

In the description of the said invention which follows reference is madeto the accompanying drawings, forming a part hereof, and in which-Figure 1 is a central vertical section of the upper part of a bottle,showing the application thereto of the improved closing device. Fig. 2is a section of Fig. 1, taken on the dotted line A A and looking in thedirection indicated by the arrow in full lines. Fig. 3 is a section ofFig. 1, taken on the dotted line B B and looking in the directionindicated by the dotted arrow. Figs. 4 to 7, inclusive, are details ofthe apparatus hereinafter described; Fig. 8 is a cross-sectional view ofa valve the elements of which are shown in Figs. 5, 6, and 7.

Referring now to the drawings, 1 is a bottle having the head 2 and theshoulder 3.

4 represents an eXteriorly-threaded collar in halves, which encirclesthe neck of the bottle immediately below the shoulder 3. To make thethreads of the two sections of the collar register one with the other,one section is provided with the cavities 5 and the other with the pins7, adapted to enter the said cavities, as shown particularly in Fig. 2.

9 is a shell, the lower part of which is interiorly threaded, screwedover the threaded collar 4, and a tight joint is effected by means of acompressible washer 10, interposed between the end of the bottle and anannular face 12, formed in the shell.

13 is a valve-chamber in the shell, having a passage 14 in communicationwith the interior of the bottle.

16 is an outlet-passage extending from near the annular face 12 to thenozzle or extreme upper end of the shell 9, and 18 the partitionseparating the valve-chamber from the said outlet-passage, whichpartition is provided with the duct 17. At the inner end of the duct 17is formed the valve-seat 19.

20 is a hollow cylindrical extension of the shell 9, with itslongitudinal center in alinement with that of the duct 17. The innerportion of the extension is bored to receive the stem 22, to which avalve hereinafter described is secured, and the outer portion contains acylindrical enlargement 24 of the stem 22. This enlargement is providedwith a slot 26, and the cylindrical extension 20 with a similar one, 27,and through these is inserted the hand-lever 29, which is pivoted at 30to the said extension, as shown in Fig. 3. A'toe 32 on the lever 29bears against the end of the I slot 26 in the opening of the valve, ashereinafter described.

Within the extension 20 and placed around the stem 22 is thepacking-washer 34 and the metallic washers 35, and between these and theenlargement 24 of the stem 22 is a coiled spring 36 to retain the valve39, hereinbefore referred to, on its seat 19.

A chain 40 connects the lever 29 with a removable cap42, which is usedonly to prevent the entrance of dust to the outlet-passage 16 in thenozzle when the bottle is not in use.

The valve 39 consists of a flanged annulus 44, an inner face view and across-section of which is shown in Fig. 5, in which is placed theflanged hemispherical plug 45,; preferably of rubber. Fig. 6 shows aface and a crosssection of the rubber plug. The remaining element of thevalve is the flanged nut 46, a rear view and a cross-section of which isshown in Fig. 7. After the rubber plug 45 is inserted in the annulus 44and the flanged nut 46 added the flange of the annulus is drawn orturned over the flange of the nut to prevent its detachment.

By reference to Fig. 1v it will be seen that the end of the stem 22 isthreaded and screwed through the rubber plug 45 into the retainingnut46. A rear view of the complete valve is shown in Fig. 4. 1

Supposing the bottle to be charged with some liquid under gaseouspressure and it is desired to discharge it of its contents, the botanannulus which is placed over the hemitle is tilted and then thehand-lever 29 forced spherical portion of the said plug with its inward,when the Valve is unseated and the flange turned over the edge of thenut, co'mliquid issues from the nozzle. When the botbined With a stemWhich is forced through the 15 5 tle is notin use, the cap 42 is placedover the compressible plug and screwed into the nut,

nozzle. substantially as specified.

I claim as my inVentionx A bottle-closing device which consists of aFRANQIS GARY flanged hemispherical plug of some compressi- Witnesses: I0ble material, a flanged nut the face of Which OREGON MILTON DENNIS,

is in contact with the flat surface of the plug, Es'rnr T. Go'r'r.
